Protection of DC Microgrid using ΔCB

Published by 1. Marwan R. Abed, 2. Oday A. Ahmed, 3. Ghassan A. Bilal, University of Technology Iraq, Baghdad, ORCID: 1. 0000-0002-1257-2810; 2. 0000-0001-7214-3412; 3. 0000-0002-5090-103X Abstract. When implementing a DC distribution network, it is much easier to integrate distributed energy sources than it is with an ac grid. Furthermore, the efficiency and reliability ofContinue reading “Protection of DC Microgrid using ΔCB”

Manage Your Energy Expenses

Published by Dranetz Technologies, Inc., Case Study Utility energy and demand costs have a direct impact on a company’s bottom line. In fact, a typical commercial or industrial facility can save from 10% to as much as 35% annually on energy costs by implementing a comprehensive energy management plan. And while each facility will require an organizedContinue reading “Manage Your Energy Expenses”

Investigating Blinky Lights

Published by Dranetz Technologies, Inc., Technical Documents he HDPQ Family of products have a number of trigger mechanisms for capturing different types of power quality phenomena. Most users are familiar with settings for sags and swells, but those typical limits usually don’t capture the “blinky lights” problems. While the Pst (perceptibility short term) parameter will indicate whether the voltageContinue reading “Investigating Blinky Lights”
